SPECIFICATION forming part of Letters Patent No. 321,245, dated June 30,1885.

Application filed April 11, 1885. (No model.)

' citizen of the United States, and a resident of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in WVindows; and I do hereby declare that the following isa full, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, which form apart of this specification, and in which-- Figure 1 is a perspectiveview showing the lower sash of a window equipped with my improvementsswung open and ready for cleaning. Fig. 2 is a perspective view showinga window-frame equipped with my improve ments, both sashes being swungopen. Fig. 3 is an elevation of the inner side of the lower end of awindow-frame equipped with my improvements, the sashes having beenremoved. Fig. 4 is a perspective view of the same, the beads having beenremoved and the hinges swung out in position for operation. Fig. 5 is avertical sectional view taken on the line 00 x in Fig. 3. Fig. 6 is ahorizontal sectional view taken on the line 3 y in Fig. 3. Fig. 7 is ahorizontal sectional view taken on the linezz in Fig. 3. Fig. 8 is aperspective view of one of the hinges detached. Fig. 9 is a plan view ofone of the hingeplates prior to its adjustment in the hinge-casting.Fig. 10 is a perspective view of the hinge end of one of the sashes; andFig. 11 is a perspective view of the lower end of the window-frameopposite to the hinge end of the sashes, the bead being removed, so asto expose the sash-cord holder and its operation.

The same letters refer to the same parts in all the figures.

My invention has relation to that class of windows in which the sashesmay slide as in the usual style of windows, while at the same timeswinging arms in the frame may be brought out to engage pintles upon thesashes, enabling the sashes to be swung inward; and it consists in theimproved construction and combination of parts of the same, ashereinafter more fully described and claimed.

In the drawings hereto annexed, A A designate the sides, and B the sill,of an ordinary window-frame. The center beads, C, and the inner beads,D, of the sides of the windowframe are each made in two pieces, andtheir lower parts,comprising in each case something more than one-halfof the entire length, are made detachable from the window-frame. Thedetachable parts of the center beads are simply seated in grooves orrecesses E in the sides A A, and the lower parts of the inner beads whenin posit-ion are retained by means of suitable turn-keys, F, engagingslotted plates G, securedover recesses H in the sides of thewindow-frame. Said keys may be provided either with permanent ordetachable handles, as shown at I and J, respectively.

The side A of the window-frame, which for convenience may be denominatedthe hinge side, is provided with suitably-shaped Inortiscs or recesses,K K, to accommodate the hinging devices L L, of which two may be usedfor each sash, located directly in front of the sashes when the latterare lowered, and they consist each of a casting, M, comprising two lugs,N N, connected by a backing, O, and in front of said backing by apintle, P, on which is journaled the hinge-arm Q,which, when not in use,is embedded in a lateral extension, It, of the mortise K. Thesehingearms consist of flat plates the outer ends of which are providedwith perforations S, and the inner ends of which are provided with slotsT, the adjoining sidesof which are provided with semi-circular openingsU, so that they may be readily adjusted and clamped or compressed uponthe pintles P. By this construction the hinges'may be produced in asimple, durable, and inexpensive manner.

It will be observed that the hinge-arms Q for the outer or upper sashare somewhat out of their respective recesses for this purpose. Theupper ends of the stiles at both sides of the sashes are also providedwith recesses Z, in which are secured the forked sash-cord holders B.The latter are so constructed that the sash-cords may be readilydetached from the free or swinging ends of the sashes.

The side A of the window-frame is provided with a recess, located underthe detachable part of the inner bead, D. In said recess is hinged aplate, D, having downwardly-inclined slots E E, in which the knottedends of the sash-cords may be adjusted and retained securely whendetached from the sashes for the purpose of enabling the latter to beswung inward.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood.

Then it is desired to swing the sashes into the room, for the purpose ofgaining access to the outer sides of the panes, the lower ends of theinner beads, D. are first detached from the window-frame. The lower sashis then raised until the hinge-arms Q may be swung out under the pintlesof said saslnwhich is then lowered, so as to cause the pintles to engagethe respective hinge-arms. The free end of the sash may then be swungout until the sashcord may be detached and adjusted in one of thenotches of plate D, after which the saidlower sash may be swung to theposition shown in Fig. l of the drawings. The center beads, C C, maythen be removed, and the upper sash connected to its hinges, and, afterdetaching the sash-cord from its free end and connecting it wit-h plateD, swung to the position shown in Fig. 2 of the drawings. The outersidesof the panes are thus rendered conveniently accessible,and thesashes may,when desired, be easily lifted oif their respective hingesand detached from the frame.

To return the sashes to their original position the operation is simplyreversed.

This device is exceedingly simple and convenient, and may be readilyapplied to windows of ordinary construction.

I am aware that windows have been 'made having the sliding sashesprovided with pintles,which may engage the outer perforated ends ofarmspivoted to swing outward from the jambs ofthe window-frame, and I do notwish to claim such construction broadly; but

I claim as my improvement 1. In a window, the herein-describedsashhinging device,consisting of a plate or casting comprising two lugsconnected by a backing and by apintle, in combination with the hingearmconsisting of a plate having aperforation at its outer end, and providedat its inner endwith a slot having semicircular recesses, whereby it isadjusted and compressed or clasped upon the pintle, substantially as andfor the purpose herein set forth.

2. The combination of the window-frame, the center and inner beadshaving detachable lower ends, the hinge-plates havinghorizontally-swinging perforated arn1s,said plates and arms beingnormally embedded in one of the inner sides of the window-frame andretained by the beads, and the sashes having plates or leaves providedwith downward-extending pintles, substantially as set forth.

3. The combination,with the swinging sashes having detachablesash-cords, of aplate hinged in a recess in the side of the window-frameadjoining the free ends of the sashes, and provided withdownward-extending notches, substantially as and for the purpose hereinse forth.

4. Asan improvementin windows, the combination of the frame, the centerand inner beads having detachable lower ends, the hinges embedded in oneof the inner sides of the frame and having horizontally-swinging armsperforated at their outer ends, the sashes having leaves or platesprovided with downward ex tending pintles, the sash-cords connecteddetachably to the sashes, and a plate hinged to the side of thewindow-frame adjoining the free ends of the sashes, and havingdownwardly-inclined notches, all arranged and operating substantially asand for the purpose herein shown and specified.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
